' My invention pertains to ;a hinge with automatic lifting'and locking means. and.

has for its-main object to providea. hinge which willenablea casement WlIlClOW to be lowered down behind the window stool, to

- makethe window istorm. proof, and-which sembled hinge is provided with means acting auto matically for locking said window in its closed. position, and which further provlded with .springmeans for automatically lifting thev window above the window stool when the Window locking means has been released, so that the window may be readily swung and opened inwardly. Another object is to. provide such a hingewith a' slotted sleeve and with a plunger or means including a locking-finger.for-locking said why dow .inits: closedposition to prevent the same from being pried openfrom-the out.- .side. r

attained with my invention, as will become apparent ..from the following description taken in connection with. the accompanying drawings, in'which. i

Fig. 1. is] an elevat-ional view'of a casement window in its-closed'position with my improved hinge applied thereto;

Fig. 2 is a vertical sectional view, taken along line 2,,2 on Fig. 1;.

Fig. 3 is an enlarged elevationa-l'view ,of the hinge mounted on awindow, with the window in its openposition; v Fig. at is a cross sectional 1ine.l-l of Fig. 3;. v n .Figs. 5 and-6 are'detail views Qftlle two .main-parts of the hinge separated or1-dis- Fig. 7 .isa detail'view of the slotted sleeve .for locking-the hinge, and the guardmemberffor the lifting spring,- as shown in Fig.3;

Fig. 8' is a cross sectional view of the locking plunger and'con-nected hinge part, taken on line 8-8 of Fig. 5; and

Fig. 9' is across sectional view-of a modified form of hinge in which the movable hinge part is mounted against the edgeof the window,

Inthe drawings my improved hinge is illustrated in connection'with a casement window including the window sashes 11 and 7 12, which, by the use of my improved hingespare swingably mounted inthe .win .dow frame 13, to engage mwardlyQofthe transom 14 and to be. movable downwardly Otherobjects and advantageous ends are view taken on behind thewindow stool15, thus preventing I therainfrom coming in under the casement l3 and having pintle barrels.18fadja-cent its" ends providing an 'extended'space therebetween, while the part 17 has a pintle barrel 19 mounted to move between-said barrels 18 and retained by means'Ofapintle-QO which may include a fixed head 21* anda removable head 22,. as'indicated in Figs. 3; and 5, the

pintle barrel 419 being shorter'than the distance between thepintle barrels 18; thus permitting the hinge part 17'to move longitu dinally onthe part 16 and on the pintle 20.

The hinge part, 17 inthe preferred form includes a part-17"farr angedsubstantially at I right anglestothe main part 17 7 thus permitting the main part 16 to. be mounted on of the window sash. as shown in the drawings; The parts 16 and 17 are provided 23 .tofasten' the hinge parts on the window frame 13 and its finishing strip 24 and on the inwardside of the window frame while the part- 17 isfastened on-the innerface with suitable vopenings for receiving screws hinge part 16 to'lower the window outward of the, window stool 15,. andis movable 'up-. wardly to the upper part 'of the pintle to clear thewindow stool and'enable the'window to' 'be swung inwardly oversaidstool.

' Meansis provided for locking the window with the attached hinge part 17 in its low-.

ered or closedposition, and this=means-is arranged to extend across the'path of, and

to engage, the movable hinge part 17 and hold it in its closed position. The construction of thisv locking means preferably n r cludesa casing 25 fastenedon or constructed integral with the stationary hinge part 16,-

and. also includes a plunger 26 slidable in a chamber 27 in said casingandihaving-a re-. dueed end or stem 28, 3Xt61lCl1]1g through a fbOl'G 27. in one end of the casing...-The

an integral curved finger'i'29 plunger has which rests against the pintle barrel19 and i has its end extending in'to a groove. 17 in hinge pa r-n17 when the window-is lowered v11o n and a spring 30 on stem 28 .automatically presses the plunger outwardlyand presses the curved finger 29. against pintle 20 in the l ablyincludesa coil spring 33 mounted on pintle aboveithe lower pintle barrel l8.

path of and above the lowered pintle barrel l9, tor-lock the windowin its closed position.

A cross pin 31 on the plunger engages in a slot 32in casing and prevents the plunger' anclfinger from rotatingout of the proper position. A. notch or bore is provided in the window frame 13 or in the sash strip 24 on said frame, for recelvingrthe casing 25 and its plunger 26, substantially as shownin the drawings; v 3 Means is also provided for automatically lifting the hinge part 17 with its attached window 'sashupwardly when'the locking finger 29 with plunger'26 is w thdrawn from itslocking position, and this means preferl 'lfhis spring is ofthe required strength and tension to automatically lift the hingepart 17 jwith theattached window sash, as soon as'the locking plunger and its curved finger are moved inwardly, thus releasing the pintle barrel '19. A guard member or sleeve 34: is mounted over spring 33 and 18 provided withan upper slot 35 for receiving the rib orliange portion 36 adjacentpintle barrel l9 of hinge part 17 when said hinge partwith the-attached window is moved downwardly into closed position. A slot 37 is provided at the lower end of sleeve 34 to receive the rib or flange portion 38 of hinge part 16,

and this sleeve thereby provides-means for i positively locking the hinge part 17- against swinging movement on hinge part 16 when said part 17 is lowered and while the locking finger 29 extends above barrel 19 to hold 1t and-the attached window in locked position.

The slot 3'? is slightly oifset from slot 35' to properly accommodate the two flanged por- -tions 36 and 38. I sleeve in position, and anycsuitable turn bolt 40 and locking member or eye 4:1 may be provided to fasten the window in closed A'knurled nut 39 holds J position.

- In the'modified form shown in F1 9" a scraighthinge part 47 is substituted for the angular hinge part. 17 and 17 of the-preferred form, thereby arranging and adapting this hinge to be fastened on the edge of the window sash as shown in said Fi 9. r i l A The other parts of the hinge are exactly the same asin the preferred form, including a casing 25 with a plunger 26 and finger. 29 thereon which has its endentering 1n a groove l? in the hinge part 47, while the window is open said finger engaglng the pintle 20., and extending across the path of pintlecbarrel 4:9 on said hinge part when j the window is closed, thus locking it in its e0 closed position; i

'It isapparent that'the hinge part 17,

.aided by theweight of the attached window,

- may be readily pressed downward against theaction of spring 33, and the attached window may therewith be lowered into its closed position to engage outwardly of the i 7 window stool 15,,and that at the same time- .the spring 30 will automatically press the I finger 29 .into locking position to retain the window positively in its closed; and lockedpositlon, sa d hlnge be ng furthermore 1e tained in said locked position by the aid of V sleeve 34 with its slots 35 and 37 and it is valso apparent that by pressing the'plunger '26 inwardlyinto casing-25, the spring will automatically raise the hinge part 17 with theatta'ched window tocl'ear the window-stool 15 and of the window.

preferably used at the lower partof each window sash only, while. the locking finger and plunger and the surrounding sleeve ermit inward swin in fins improved hinge 1s 1 areleft off from the hinges at the upper part I pocket with a slot, a second part =with' a pintle barrel movable between the spaced barrels longitudinallyon said =pintle, V a' plunger providedwith a spring in, said pocket and with transverse-means slidable in said slot to prevent rotation therein,said
